For this “Greater-Than Sudoku,” we’re not givin’ you any numbers to start off with! Adjoining squares in the grid’s 3-x-3 boxes have a greater-than sign (>) telling you which of the two numbers in those squares is larger. Fill in every square with a number from 1–9 using the greater-than signs as a guide. When you’re done, every row, column, and 3-x-3 box will contain the numbers 1–9 exactly one time. (Solving hint: try to look for the 1 and 9 in each box first, then move on to the 2 and 8, and so on.)
